Step 1
Find the area of one equilateral triangle
Applying the law of sines
![Area=\frac{1}{2} *a*b*sin C](https://tex.z-dn.net/?f=%20Area%3D%5Cfrac%7B1%7D%7B2%7D%20%2Aa%2Ab%2Asin%20C%20)
in this problem
a=b=7 cm
C=60 degrees
so
![Area=\frac{1}{2} *7*7*sin 60](https://tex.z-dn.net/?f=%20Area%3D%5Cfrac%7B1%7D%7B2%7D%20%2A7%2A7%2Asin%2060%20)
cm²
Step 2
To calculate the area of the hexagon multiply the area of one equilateral triangle by ![6](https://tex.z-dn.net/?f=%206%20)
cm²
therefore
the answer is the option
73.5 sqrt 3cm²
To solve this problem, you need to use the Phythagorean theorem c^2 is equal to the sum of a^2 and b^2. If a less than or equal to b and b is less than or equal to c or a^2 plus b^2 is greater than c^2 then it is an acute angle.
